Hi ALO. I like mine. Had it for about 5 years. Added an AXA quick change tool post, that's about the only change. I've made steel and aluminum parts, finish is what you'd expect from a small...

I think it was around 3000 CAD...Complete parts list to build a high speed DIY laser PR530 - Lightobject.com Support Forum

Check out Lightobject.com Support Forum - Index page There is a list in one of the sub forums of all the items required to build a laser. Or buildlog.net - CNC Laser Buildlogs. I've built my own,...

It is a good system.

My workflow goes like this: CorelDraw X15->LaserCad->DSP->Finished product

LaserCad is NOT a very intuitive program, at least not for me. The documentation is difficult...

Interesting concept, good idea.

How much goes back to the designer?

AFAIK, the G540's just run hot. And yes, two seperate builds. The prior machine had the G540 on it. My current machine has DQ860MA's and NEMA 34's. I did a run yesterday, 5 hours non stop. The...

Good job on the BOM but i dont see a power supply. Instead of using a large PS for my last build, I used two smaller ones (48v). I hooked one of them to the Z and A axis, the other to the Y and X...

The dial gauges are an excellent idea! Good stuff!

i dont think i used plated nuts. It probably wouldnt matter.

The epoxy adventure did NOT work very good for me.

I had a nice cool day (about -38 deg C). I cooled my workshop down to about 10 deg C. so the pot life of the epoxy would be as long as possible....

In my last post, I said that I had to tap the nuts into the holes. I meant "tap" like "tap tap" with a hammer. Not a tap. LOL. Sorry for any confusion. :rolleyes:

Epilog lasers are great. Epilog lasers are expensive. I built my own for about 4000.00 and it will do anything the Epilog will do (umm, probably not, but it will do anything that I want it to do). ...

Yes, i guess they would fall into the holes if not welded in. I had to tap the nuts into the holes, a 5/8 drilled hole is a tight fit for the 3/8 nuts. I threaded a 4 inch long bolt into them, then...

I dont have pictures of it, but I drilled 5/8 holes in the top of the rails, and welded in 3/8 NC nuts. That way I could attach my rails. Because I had welded to the underside of the rails anyways,...

Hello

This will be my 3rd build, the first being a JGRO, the second an all steel welded 27" X 43", and this one is going to be 60" X 110".

Heres some pics of the "Pile-o-Steel"

I'm in Alberta. But used to getting raked over the coals on shipping. I dont think I would build my own power supply, I'm not that great with electrical things. Unless you know of a good...

I am currently building a 5x9 CNC router table, and will have 4 stepper drives to control the axis, 2 on x axis, 1 each on y and z. I have been looking for a larger unregulated toroidal power supply,...

Thanks Doorknob. I read through the G540 documentation (I also own one of those), and gleaned this tidbit:

Before beginning, be sure to have a suitable step motor, a DC power supply suitable...

Quick question (and yes, I searched):rolleyes:

Can the stepper driver with the following specs:

•18 to 36VDC Supply Voltage
•H-Bridge, 2 Phase Bi-polar Micro-stepping Drive
...

Hi guys

A couple of updates...I have updated the router from a Bosch Colt variable speed to the Hitachi M12-VC. It dramatically increased my cutting speed. It at least doubled it. I have also...

I started out with the JGRO machine. It was a good eye opener, and let me know what is possible with common 1/4 all thread. If I did it all over, I would still go the same route. I did cough up...

I had the same problem with my bosch colt, it was loose where the bottom bearing is. By loose, I mean that if I pushed the bit back and forth sideways, it would make a clicking noise and move about...

Sure they're similar...they both cut up wood! LOL

Yours looks a bit more pro though. And its green. :-)

What are you using for your rails?

I believe that unit doesnt have the 25 pin printer port, but you could probably use a usb card set up like louieatienza suggests. I dont have any experience with usb, but i do have a Toughbook CF28...

Nice work so far Tom. Are you going to be using CRS rails for your x and y axis?

Thanks Carveone. It really wasnt too hard to weld it up, I didnt have any fancy jigs or even a large flat table to weld it up on. I did it on 2 wooden sawhorses. (flame2) I just took my time and...

Hi Gents, guess it's time to show what I have been up to. But first, a little history...

I started into the machinist trade back in 1995. I was never involved in any CNC work however, all...

Two examples of some "thinking outside the box". Very nice work gents!

Gents

I've been using my little MDF JGRO for the past couple of months while learning this new hobby (obsession) of mine, and get a bit bugged with the vacuum cleaner hose hanging down in front of...
